RR Donnelley — One Big Green Machine

RR Donnelley has also invested in the latest oxidizers to control emissions and reduce natural gas usage, while still achieving better overall performance. Worldwide, more than 50 such oxidizers have already been installed in its facilities, with close to another dozen planned for installation. The curently installed oxidizers alone will save the equivalent of 6.7 million gallons of gasoline each year. That's equal to the amount of gas a fleet of nearly 12,000 cars would use annually.
